Modifying the FT-897 to get the best from it.

I have been using my ft-897 for a while now, the main rig has a fault and I have been far too busy to get it sorted and repaired.

The good news is though that my hobby has been there to allow me to escape and relax when needed, I often find that the hobby of radio offers us an escape from normal everyday life in many ways. Sometimes the ability to go and sit and listen to some CW with the headphones on and hide away from family noise for an hour is always welcomed. I am enjoying my Begali key and trying to work some rare DX when time allows and I am lo
